Infiniti announced the world’s first production-ready variable compression ratio engine.

With the ability to continuously transform, INFINITI's VC-Turbo technology uses an advanced multi-link system to seamlessly raise or lower the stroke of the pistons, detecting the car's driving condition and driver inputs, and instantly selecting the most suitable compression ratio. The engine is able to offer any compression ratio between 8:1 (typical for high performance engines) and 14:1 (used by many manufacturers for high efficiency).
